  • On 28 April 2008, a male Himalayan Swiftlet (Aerodramus brevirostris) was captured and examined at a night roost of swallows on Hongdo Island, Jeollanam-do, Korea. This is the first record of this species from Korea confirmed by specimen examination. We describe morphological features and some phylogenetic notes of the Himalayan Swiftlet found.

  • In this study, the phylogenetic relationships among the genera Alsidium C. Agardh and Bryothamnion $K{\ddot{u}}tzing$ were investigated. Phylogenetic analyses using the plastid-encoded markers rbcL, psbA, and the mitochondrial barcode region (COI-5P) resolved a well-supported clade that included the species Alsidium corallinum, Bryothamnion seaforthii, and B. triquetrum. Our results indicated that taxonomic recognition of the genus Bryothamnion is not supported and two species of Bryothamnion are reallocated to Alsidium. A reexamination of the morphological definition of Alsidium is provided with an updated diagnosis of the genus and a morphology-based comparison of species that are currently circumscribed under this generic name. Furthermore, we reviewed morphological differences and similarities between Alsidium and the genus Digenea, both belonging to the tribe Alsidieae, discussing the most relevant morphological characters.

  • Hainan is the second largest and southernmost island of China, and it harbors many species of the family Gracilariaceae. In this study, we conducted molecular and morphological analyses of gracilarian specimens collected from Hainan Island, to clarify their taxonomic identity and phylogenetic relationships. Five species of Gracilariaceae in Hainan were determined through maximum likelihood and Bayesian analysis of rbcL sequence data. Based on the phylogenetic trees and morphology, Hainan specimens were identified as three species of Gracilaria, one species of Gracilariopsis, and one species of Hydropuntia, namely, G. salicornia, G. tenuistipitata, Gracilaria sp., Gp. bailiniae and H. edulis. This is the first report of the molecular phylogeny of Gracilariaceae on Hainan Island, and it helps to clarify the taxonomy and distribution of gracilarian species in the Asia-Pacific region.

  • Macrofungi are essential decomposers in the forest environment. Although more than 70% of the land is mountainous, there has been a lack of research on mushroom diversity in Korea compared to the global species estimation. For this reason, the need for further research became apparent. The surveys were conducted from 2014 to 2022 nationwide. As a result, 15 unrecorded macrofungal species were discovered: Agaricus thiersii, Baorangia alexandri, Boletellus putuoensis, Entoloma bulakhae, Entoloma pygmaeopapillatum, Entoloma subtenuicystidiatum, Gerronema kuruvense, Hyphoderma nudicephalum, Hyphoderma tenue, Macrolepiota subcitrophylla, Mycena jingyinga, Mycena yuezhuoi, Ophiocordyceps vespulae, Scytinostroma acystidiatum, and Steccherinum straminellum. These species are identified based on morphological, molecular, and phylogenetic analyses using the internal transcribed spacer (ITS) region and the nuclear large subunit rRNA (LSU) region. Here, we provided macro- and micro-morphological figures with phylogenetic trees to support 15 species as unrecorded to Korea.

  • 광대버섯 Lepidella 아속은 독광대버섯군 (Sect. Phalloideae)가 속해있는 것으로 잘 알려진 그룹이다. 그렇지만, 국내 광대버섯 종의 분류학적 연구는 여전히 진행 중이다. 이번 연구에서, 우리는 국내에서 2009년부터 2015년까지 수집된 광대버섯 표본 중 형태학적 기반으로 Lepidella 아속에 속하는 22 표본을 분석하였다. Internal transcribed spacer (ITS) 영역의 염기서열을 기반으로 분자유전학적계통분석을 진행한 결과, 16종의 분류군이 동정되었으며 이 중 국내 미기록인 Amanita sepiacea, Amanita modesta와 Amanita kotohiraensis가 포함되어있었다. 처음 보고되는 3종의 현미경적 특징은 기록과 함께 이미지를 저장하고 삽화를 그렸다. 본 연구에 사용된 모든 표본은 국립농업과학원 표본실에 보관되어 있다.

  • Morphological features of larvae and pupae of twelve species of Simulium (Simulium) from Korea are investigated and redescribed. Detailed descriptions of immature stages of each species are provided with photographs. For the Korean members of subgenus Simulium, combinations of the following characteristics can be used to separate them from other Korean subgenera: larval abdomen without a pair of conical-shaped ventral tubercles; postgenal cleft variously shaped, viz., miter shaped, spearhead, bullet shaped or triangular; rectal papillae 3 simple lobe or compound lobes; pupal gill of 6-16 filaments; cocoon shoe, boot or slipper shaped; and head trichomes 3 pairs (1 facial+2 frontal). Habitat information and other ecological aspects of each species are provided. Updated keys to larvae and pupae of the Korean species of the subgenus Simulium are also provided to facilitate species identification. Taxonomic treatment based on external morphologies of larvae and pupae of Korean species of the subgenus Simulium are focused and included in this study. To understand their interspecific relationships, phylogenetic analyses using multiple data from molecule, morphology, and ecology are warranted in future research. Also continued exploration for new character systems is needed to establish more stable boundaries for subgenus and species delimitations.

  • The cycle of the seminiferous epithelium and spermiogenesis in three species if the genus Crocidura, the lesser white-toothed shrew, C. suaveolens, the Japanese white-toothed shrew, C. dsinezumi and the big(=Ussuri) white-toothed shrew C. lasiura, in the breeding season were studied with light and electron microscopes. The three species examined are distinguished from each other in the morphology of the seminiferous epithelium and the spermiogenesis, suggesting that these morphological characteristics are useful for the identification of the species. C. dsinezumi and C. lasiura, however, share many characteristics which are not common in C. suaveolens, as follows: In both species, 1) the cycle of the seminiferous epithelium is composed of 10 stages against 11 stages in C. suaveloens; 2) the earliest intermediated type spermatogonia is observed at stage I against stage III in C. suaveolens; 3) the spermatids of step 5 is observed during the stages V-VI against stages V-VII in C. suaveolens; 4) the acrosomal extension occurs during the stages VIII-X against tages IX-XI in C. suaveolens; 5) the condensation of the nucleus occurs simultaneously whereas it begins from the middle and along the nuclear membrane in C. suaveolens; 6) the capitular length in acrosome phase is shorter(about 2/3 of the diameter of the proximal centriole) than in C. suaveolens(longer than the diameter of proximal centriole; 7) length of the post nuclear cap is shorter(less than a half of the nucleus) than in C. suaveolens(about a half on the nucleus). Hudging from the similarities in the spermatogenesis in C. dsinezumi and C. lasiura, the relationship between them seems to be close compared to those with C. suaveolens.
